Well in pregnant again after a miscarriage

I miscarried on Dec 6th and I'm now prego. My last neg test was Wednesday then yesterday (Sunday) I got very faint lines and a digital one that said pregnant... I'm hoping and praying to God that this is a healthy pregnancy and whenever I go to my first appointment there's a baby and a heart beat. I guess I'm only like what 1-2 weeks? I had no period in-between... Anyone else go through this with a positive outcome?...thanks
